The only problem with your scenerio is the indian is only growing food for his immediate family and maybe village.
Farmers tend to be the great planners, they are always looking at trends what's going to happen 6 months, next year, 2 years from now. They are constantly watching the weather patterns, trying to guess if they are going to get the harvest in before rain makes the field to muddy, the moisture contint in the grain to high....
